Answer:
B
Step-by-step explanation:
Well you first know that your y-intercept is -2 (look on the graph) so you can automatically cancel out option A and D. Now this leaves us with B and C. The only thing that is different between the two answers is the slope. Slope = Δy/Δx (change in y divided by change in x) So from (0,-2) to the next point (4, -1) How far is the x and y? Well you go up one and to the right 4. the change in y is up one (+1) and the change in x is right 4 (+4).
You can also do this
\frac{-2-(-1)}{0-4} = \frac{-1}{-4} = 1/4\\
(y2-y1)/(x2-x1) (the numbers are subscripts)
